The function f = {(1,2),(2,3),(3,3)} is one to one because every x value is different. The x values are given to be 1, 2, and 3.
The function g = {(1,0)(2,3),(3,2),(4,8)} is also one to one because every x value is different. The x values are given to be 1, 2, 3, and 4.
Both relations are one to one functions.

The given relation f is not one-to-one function, since two different inputs "2" and "3" have the same output "3".
The answer of the other tutor related to the relation "f" is not correct.
